My innovation were wireless transmitters. As someone who is using devices which are connected to the Internet all the time, the ability to not be plugged in is very important. Although wireless transmitters have existed for about 100 years now, (@Marconi), almost every device has the ability to transmit information wirelessly now. It's not always perfect though. For one device to be wireless, there has to be another device somewhere that it can reach a signal from. As in, if a satellite isn't over head, or a tower anywhere near, a cellphone won't work to well.
My dad choose handheld devices (smartphone, tablet, etc) as his innovation. As an airline pilot for the past 20+ years, the way his job has changed by the introduction of the Internet is incredible. He used to have to carry around a huge binder with info about every airport and runway, now it has all been crushed down into an app on his company iPad. All of the work he does with the plane can all be found on his iPad. Seeing as most airline pilots are nearing their 60s, the sudden introduction of this technology was tough.
Mobile devices pretty much rely on wireless transmitters to exist and function. Without them, the point of a handle device wouldn't exist. The ability to have the entirety of humanity's knowledge in your pocket exists because the internet can be accessed anywhere. More and more satellites are being sent into space to help spread this even more around the planet.
